Fix Unicode string normalization with null bytes

Fix Unicode string normalization with null bytes

Previously, String.prototype.normalize constructed its ICU input
string as a null-terminated string. This creates a bug for strings
which contain a null byte, which is allowed in ECMAScript. This
patch constructs the ICU string based on its length so that the
entire string is normalized.
